A significant and comprehensive work on the folklore and healing properties of gemstones.--description submitted for Facets of GIA exhibit.
"An encyclopedic, durable work [...] Apparently Kunz meant this work and its
companion volume, Magic of Jewels and Charms [...] to be the ultimate
compilations of everything worth knowing on the curious lore of gemstones, and
in justice to his effort, it can be said that no works compare to them, even to
this day."--Gemology by J. Sinkankas, entry no. 3693.
